  2. 16. Controlled release gel formulations and preclinical screening of drug candidates

    Author : Tofeeq Ur-Rehman; Gerhard Gröbner; Mikael Elofsson; Åsa Gylfe; Martin Malmsten; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; poloxamer; drug delivery; micellization; DMSO; calorimetry; NMR. in situ gelation; chitosan; preclinical pharmacokinetics; type III secretion inhibitors; Physical chemistry; Fysikalisk kemi; Pharmaceutics; galenisk farmaci;

    Abstract : Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermo-reversible poloxamer gels, which are suitable for novel drug delivery applications.

  4. 17. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

    Author : Thitiwut Vongkampang; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor kronotskyensis; volumetric hydrogen productivity; non-diauxic; acrylic fibres; cell immobilization; chitosan; biofilm; c-di-GMP; cellobiose; xylose; consolidated bioprocessing; heat-treated wheat straw;

    Abstract : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. READ MORE

  5. 18. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology

    Author : Niklas Nordgren; Mark Rutland; Harry Brumer III; Robert Pelton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; afm; surface force; friction; composite material; model surface; quartz crystal microbalance; dissipation; cellulose; xyloglucan; chitosan; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; graft; fiber; thiol; spring constant; calibration; lubrication; polyion; responsive.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied.  The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE

    Author : Maria Wennman; Mikael S. Hedenqvist; Anna Justina Svagan; Mårten Hellberg; Wim Thielemans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte complex; binder; chitosan; carboxymethyl cellulose; citric acid; nonwoven; tensile strength; hydrophobicity; Polyelektrolytkomplex; bindemedel; kitosan; karboximetylcellulosa; citronsyra; nonwoven; dragstyrka; hydrofobicitet; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nonwovens are textile-like materials with similarities close to paper. One significant sector where nonwovens are used is for single-use products such as wet wipes and hygiene products. With an increasing global population, the manufacturing and use of nonwovens have grown significantly. READ MORE
